| 1328 EXPERIMENTAL DEPARTMENT. Rm{William Robotham - Chief Engineer}/TAS.{T. Allan Swinden}24/JH. 21st. February, 1939. Messrs. Henry Wiggin & Co.Ltd., Thames House, Millbank, LONDON.S.W.1. Dear Sirs, We should be obliged if you would forward to us a copy of your Data Book concerning Wilco-Wiggin Thermometal. We are primarily interested in a temperature range of 0 - 100°C, and we should be glad to know whether a bimetal strip is available which will withstand corrosion in (a) water, and (b) an antifreeze solution such as 40% glycol, and if not whether a protective plating treatment completely upsets the characteristic of the thermometal. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
